Fascinating article and something I’ve done off and on.
OT: I was reading a GlyNAC study and was stunned at the doses. 100mg/kg/day. For a 150 pound man it would mean almost 7g of each. That’s a lot. Are there other studies showing a lower minimum effective dose?
Nestle’s Celltrient division says to take two 600 mg doses of glycine and NAC a day, for 1,200 of each a day. They licensed the patent and apparently believe this lower dose is fine.
I would say they market it to all ages, though.
The effects are likely additive. My wife and I take 1,800 mg of each a day and we’ve noticed a benefit.
It’s cheap enough that the higher daily amounts could be fine and financially attainable for older people, like those used in the studies, as they have a greater bodily need for glutathione and possibly the separate components, for what they can also do alone.
It appears multiple smaller doses throughout the day are the better approach, as there is a limit to the amount of glutathione cells need to produce, every few hours.
